Hey guys,

So a few days ago i installed FTB Ultimate Reloaded and also installed OptiFine and SEUS Renewed Shaders. It all worked fine for a few days. The weird thing is since yesterday i get these weird shadows showing up only on one part of the map (so far) and thats sadly the island i settled on with my friends (We're playing on our own server).
I already checked every shader setting and also different OptiFine versions for Minecraft 1.12.2 (F5 and E3). Also i tried different shaders but there the same issue occured. I have turned clouds and cloud shadows off so this cant be the issue. Does anybody know why this occurs? Does it have anything to do with some mod from FTB Ultimate Reloaded maybe? It is also probably not specific to my PC as the same issue occurs on my friends PC but also just since yesterday....

Another problem thats probably specific to my PC is that everytime Minecraft utilizes more than 90% of my GPU i get really weird artifacts in from of colored dots flashing all over the screen eventually leading to a crash. I can not intentionally recreate this though. I have to limit minecraft to 75 Fps so this doesnt happen once every while and I only have 60-80% GPU Load....i dont have this issue in other very demanding Games so its a bit weird....my GPU seems to be working fine outside of Minecraft.
My GPU Temps dont go over 80°C and my CPU doesnt exceed 60°C so heat shouldnt really be an issue if im right...

Here are my Specs if needed:

I7 8086K @5 Ghz
ZOTAC GTX 1070 AMP (not overclocked)
16 GB Corsair Vengeance RGB 3200 MHz
MSI Z370 GAMING PRO CARBON

I allocated 8 GB of Ram to FTB but changing this doesnt affect any of my issues....
Also FTB is running of of my system drive which is some Samsung M.2 drive...if this is of any importance.

PS: Sorry for bad english, I'm german
